For this week, Decision Science News has created a video tutorial on how to get started using the R Language for Statistical Computing. (The tutorial is best viewed in your browser’s full-screen mode, try pressing F11 in Windows). R is free and open source, and constantly being improved upon by countless contributors worldwide. DSN highly recommends using R.

Topics covered include:

- Downloading and installing R in Windows
- The R graphical user interface
- Viewing the graphics demo
- Vectors and basic stats

The commands in the tutorial are:

demo(graphics)

x=c(1,2,3,4,5,6,7)

y=c(10,14,20,18,16,15,10)

x+y

z=c(x,y)

sum(y)

mean(y)

sd(y)

plot(x,y)

barplot(y,col=”lightgreen”)
